Fast, Professional, Friendly




Review of Black Diamond

We are very pleased with our service today! I called at 5pm yesterday to report our clogged drain. I was connected directly with a human (no voicemail run around) who said they could send someone out in a few hours with an after hours service fee, or at 8am the next morning at standard pricing. Since we didn't have an active leak, I decided we could live until the next morning without the kitchen and opted for 8am. Dave showed up on time, got right to work, had all necessary parts and equipment on hand, was extremely clean and professional, and he had us up and running by 10:30am. We will absolutely use Black Diamond again in the future and highly recommend them!

A safer house




Review of Black Diamond

Thanks to teamwork among the different business segments of Black Diamond, our house is safer. We didn't know that the flexible aluminum dryer vent was clogged with lint - a major cause of house fires. That was found by a Black Diamond electrician who was installing a circuit breaker box (to replace an old fuse box - another source of house fires). We were called by Black Diamond to arrange for an HVAC specialist to come out the next day and install new, modern solid ventilation from the dryer to the outside. Money well spent. We can always count on Black Diamond!

Great Service by Friendly, Knowledgeable Company & Technician




Review of Black Diamond

Setting up an appt. for the check/clean of our furnace was easy w/ a minimal, amount of wait time for the appt.to occur. Keo, the Black Diamond technician, arrived promptly, was smiling & friendly & displayed his experience with ease. Afterward, he filled me in on his findings, brought me up to date on the furnace's condition and left the area he worked in clean and free of work materials! I highly recommend this company as well as their technician, Keo! Job well done!

Electrical




Review of Black Diamond

I had an electrical problem with a switch and outlets. I called Black Diamond because they have always been my go to company for any type of repair. They didn’t disappoint. They were able to get her within the week. Tim and Tony were great! For a problem that could have been expensive. They were able to deduce the problem and promptly repair it. It was neutral wire that was not connected to anything. The price was reasonable and service was great.


Keo is the best!




Review of Black Diamond

Review of Black Diamond

We had a lot of jobs to do over the last years and it was always a pleasure to work with the specialists from Black Diamond. They are fast in emergencies, reliable in their appointments and work and all of the specialists are super friendly and helpful.
